Pfizer-BioNTech to seek authorisation for 3rd booster shot

Pfizer and BioNTech announced on Thursday they would seek regulatory authorisation for a third dose of their Covid-19 vaccine.

It comes after initial data from an ongoing trial showed a third shot pushed antibody levels five to 10 times higher against the original coronavirus strain and the Beta variant, first found in South Africa, compared to the first two doses alone, according to a statement.
